Inspection Summary:
Everything looks in good shape with the only question being sample point (2)? outfall location. Mr. Cannady wanted to be
sure he was capturing a full representation of the runoff for that outfall. We talked about adding core fiber baffles beyond the
outfall pull that exists on the SW corning of the property next to the train track. This would alow them to add an additional
filtration devise since the water in the basin stays so murky and would probably never provide for a TSS sample below the
benchmark. This may require digging a small channel beyond the basin
